Automatic Irrigation System Using Wireless Sensor Networks

Gaurav Soni, Navdeep Singh

Wireless sensor networks have become an important tool for modern growers. Sensors provide the ability to monitor conditions from the farm-level down to individual plants. Such sensors include ambient temperature, humidity, soil water content, irrigation pressure, applied water volume, and fertilizer concentration. Commercially-available wireless sensor networks for agriculture have until recently focused on sensor monitoring, but not control. Growers using these systems have a wealth of crop information from sensors, but must implement control decisions using traditional means such as stand-alone irrigation controllers or manual labor. Wireless sensor networks (WSNs) find wide applications in environmental monitoring. MAC protocols play a vital role in controlling the energy consumption in a WSN. It tells the network when and how to access the medium. Time Division Multiple Accesses (TDMAs) are well suited for these real time applications. Because it prevents radio interference, and reduces energy consumptions. In this paper we reviewed the Basic Architecture of Automatic irrigation system using of WSN and some applications of WSN.
